The GRM219B31C475KE15D is a multilayer ceramic capacitor (MLCC) manufactured by Murata Electronics North America. MLCCs are fundamental components in electronics, used for a variety of functions including decoupling, bypassing, filtering, and energy storage.

Applications

• Decoupling: Stabilizing voltage supplies for ICs by filtering out noise.
• Bypassing: Routing high-frequency noise signals to ground.
• Filtering: Removing unwanted frequencies from signals.
• Smoothing: Reducing voltage ripple in power supplies.
• General Circuit Applications: Suitable for diverse electronic circuits requiring capacitance.

Features

• Capacitance: 4.7µF (4.7 microfarads).
• Voltage Rating: 16VDC.
• Temperature Characteristic: X7R. This is a Class II dielectric, which provides a good balance between capacitance stability and size. The capacitance changes within ±15% over the operating temperature range.
• Size: 0805 (2012 Metric). This specifies the physical dimensions of the capacitor: 0.08 inches x 0.05 inches (2.0mm x 1.2mm).
• Termination: Nickel barrier with tin plating for reliable soldering.
• RoHS Compliance: Compliant with the Restriction of Hazardous Substances directive.

Benefits

• High Capacitance Value: Provides a relatively high capacitance value for its size, suitable for applications requiring significant energy storage or filtering.
